从 Mac 中删除 Java 8 JDK [英] Removing Java 8 JDK from Mac

问题描述

所以我前段时间安装了 JDK 8 的测试版来查看一些示例.我现在肯定地认为，在版本之间进行更改很容易.

So I installed the beta of JDK 8 a while ago to look at some of the examples. I thought for sure by now, it's easy to change between versions.

使用 IntelliJ 进行一些 Play 开发.出于某种原因，尽管 IntelliJ 使用 8 进行编译:

Doing some Play development with IntelliJ. For some reason, IntelliJ is compiling with 8 even though:

• 我在 Preferences 中将编译器设置为使用 1.6
• 据说它通过外部构建使用 SBT，但命令行中的 sbt 有效
• JAVA_HOME 指向 JDK 6.

如果我转到 Java 首选项页面，它确实显示已安装 8，但没有卸载它的选项，也看不到任何其他版本.

If I go to the Java Preferences page, it does show 8 installed, but there is no option to uninstall it and it doesn't see any of the other versions.

当我做 which java 时，它告诉我 /usr/bin/java 而我做 /usr/bin/java -version它返回 1.6.

When I do which java, it tells me /usr/bin/java and I do /usr/bin/java -version and it returns 1.6.

注意:稍微摆弄一下，您可以使用 IntelliJ 和 JDK7，参见 此处.

Note: with a little fiddling, you can use IntelliJ and JDK7, see here.
